I agree with Audiokinesis and Learsfool - the Model 14 is probably going to sound the most similar to the Model 19, although there are still big differences.
Consider your room. The 19s are huge. Unless you have a really large space the 14s might be better. Upgrading or rebuilding the crossovers will result in the loss of some muddiness in the mid and upper ranges, but unfortunately the 14s will never produce the same low-end extension of the 19s.
